The mean of the sampling distribution will be u, (i.e., the same as the population mean)
and
the standard deviation of the sampling distribution will be
(that's the population standard deviation
divided by the square root of the sample size).
In the AP Stats Guy video, he talks about the number of text messages his students send during class. Suppose the
average number of text messages his students send during class is u = 30 text messages. If we take samples of say, n =
36 students at a time, we would expect the mean of the sampling distribution we create to be the same as the population
mean, 30 text messages.
If we can further say that standard deviation of the number of text messages is 12 text messages, by how much would we
expect the sample means to vary? (hint, use the formula above)
